Thanks for that link Twisty! Although we winterized our rig today, I just ordered one so I am ready for next year. Not sure how the same device works for a 5" or 10" system but for $20 and some change I'll give it a shot.
The 5 or 10 inch dimension is for the height of the filter. The top OD is a common dimension.
Sears has tons of stuff - still.

I'm sure my system if very similar to yours. So, a few days ago I removed my inside filter canister and replaced with two gator push on type elbows and a straight piece of pex pipe (the newer type of pex pipe). It took longer to go to the hardware store than it did to replace the filter canister. I've been using an in-line water filter for over a year now. It will sure be easier to winterize now! I can take a picture of the work I did if it would help.
I did the same thing. After laying on my back and slidding into the front storage to remove the filter i said this is the last time. The gator fittings work great.
